MOLD-SUPPORT.

To all whom t may concern:

Be it known that 1, JULIUs DUNNER, a Russian, now residing in the United States, residing at Brooklyn, in the county of Kings and-State of New York, have invented new and useful Improvements in Mold-Supports, of which the following is a specification.

This invention relates to a structure for supporting articles to be stuffed, the invention being more particularly related to a novelautomatically operated device for supporting ball forms, doll and .other forms, while they are being stuffed with filling material.

The principal objects of the invention are: (1) the provision of a device of this character, which is adaptedA to be efliciently employed in connection with y my stufling machine, for which application for patent was led on Dec. 26, 1918, Serial No. 268,428, in order rapidly and uniformly to stuff ball forms, doll and other toy forms; (2) the provision of a device which is adjustable in order at will to vary the degree of compactness with which the stuliing is eected; and (3) .the provision of a device, wherein a spring-pressed shaft or pedestal is arranged to support the forms to be stuifed, wherein a pair of coperating members vare mounted so as to resist the movement of the shaft or pedestal until the inserted material has been subjected to a predetermined pressure, and wherein the resistance to the movement of the shaft or pedestal may be readily varied so as to render the device capable of use in connection with a wide variety of stuffing operations.

With the foregoing objects in view and Others, the invention resides in the details of construction and in the arrangement and combination of parts hereinafter described, defined in the claims, and illustrated in the accompanying drawings, forming a material part of this specification, and in which :n

AFigure' 1 .is a view in side elevation of the invention in connection with my stufling machine as above referred to, parts being shown as broken away.

Application filed December 26, 1918. Serial No. 268,427.

treadle is depressed and elevated, respectively.

Fig. 6 is a fragmental detail view, showing a mold holdingv the form or cover of a toy ball, which is to be stuffed.

Referring more particularly to thev accompanying drawings,vthe` numeral 10 denotes a base-plate, cast at one end with an upstanding lug 11, and rigidly carrying, in advance of the lug, an upstanding hollow pedestal or shaft 12. Fitted in the pedestal 12 for longitudinal movement therein, is a shaft or column 13, which is normally urged upwardly by a push spring 14, disposed within the pedestal 12 so as to act upon the end of the shaft 13. Upon the top end of the pedestal 12, there is secured a collar 15, cast with the projecting lugs 16 and 17, of which the latter projects flush with the top edge of the collar. The collar is also cast with a concentric upstanding sleeve 18, which loosely embraces the shaft 13, and which is provided in diametrical relation with longitudinal guide slots 19.

Fulcrumed at 20 to the base-plate lug 11 is a treadle 21; and pivoted at 22 to the collar lug 16 is a pressure lever 23, the top edge of which toward its outer end is provided with a plurality of notches 24 which are identified by numerals progressively increasing toward the outer end as shown. Pivotally connected to the treadle at 25 isa resistance bar 26, to which the pressure lever 23 is fulcrumed at 27, this' bar above the pressure lever having an enlarged wedgeshaped extremity 28.

Extending across on opposite sides of the wedge-shaped extremity 28 are the outer ends of the tong members 29 and 30, formed intermediate their lengths with the inwardly projecting lugs 31, holed through to receive the axis 32, which is bolted to the bracket lug 17. Forward of the lugs 31, these mem'- bers 29 and 30 diverge so to straddle the sleeve 18. Secured on the inner side of the end of each member, is an arcuate shoe 33, which lits in a guide slot 19'so as to frictionally engage the sli-aft 13. 1n view of the form of the tong members, thu'sfcoperatively connected and pivotally supported', it will be Obvious that when the wedge-shaped extremity 28 is drawn downwardly, the shoe 33 will be frictionally tightened upon the shaft 13, the degree of frictionalengagement with said shaft depending upon the relative spreading apart of the rear ends of the tong members under the downward movement of the wedge-shaped extremity 28. Also, it will be observed that by depressing the treadle 21, the wedge-shaped extremity 28 will be elevated above the members 29 and 30, with the result that the shoes 33 will be withdrawn from tight frictional engagement with the shaft 13.

Mounted upon the top of the shaft 13 is a table 341, on which may be placed a mold as 35 or other suitable structure, capable of properly holding the form or shell to be stuffed. F or the purpose of illustration only, l show disposed in the form 35 a ball form or shell 36, which is to be stuffed with sawdust, cork or any other suitable filler, consisting of small particles adapted to be packed and conpressed to provide a substantially solid interior when the cover is sewed together.

The material with which the ball is to be stuffed is mixed in the hopper 37 and then pressed into the form 36, by means of a screw 38 which revolves in the funnel 39. The mechanism for mixing the filler in the hopper 37 and for operating the screw 38 are set forth and described in detail in my patent application for stuffing machine, above referred to. It is sufficient here to note that the screw 38 conducts the ller downwardly through the funnel 39, first dropping it into the form and then, as the form fills up, pressing it therein. Being ixedly carried against upward movement, this screw, as the form fills up, forces the shaft 13 downwardly. In order to resist the downward movement of the shaft as may be necessary to enable the screw to press the filling in the form with the degree of compactness desired, a weight as 40 is swung from one of the notches as 24.

Now, the numerals set opposite the notches may represent ounces, pounds or fractional parts thereof, indicative of the weight which must be swung therefrom in order to obtain a substantially equivalent pressure of the screw upon the accumulating filler material before the downward movement of the shaft is effected.

When the shaft has been forced downwardly through the filling of a form as 3G, the mold 35 may be readily removed, and another mold carrying another form to be filled, placed in proper position upon the table 34C. By depressing the treadle 21, the tight engagement of the shoes 33 upon the shaft is released, permitting the spring 111 to re-position the shaft 13, so that the funnel 39 and screw 38 enters the new form to be filled. lt will be understood, of course, that immediately the foot is removed from the treadle 21, the weight will cause the elevation of the same, and in conjunction therewith bring the shoes again into tight frictional engagement with the shaft.

Vifhilc, for the purposes of illustration, I have herein shown but one mold, designed to hold a ball form while it is being stuffed, it will, of course, be obvious that a great variety of molds may be similarly employed, and that the same may be designed to properly hold such articles as doll body forms, doll limb forms, cushion forms, and a great variety of articles.

Having thus described my invention, what l claim is 1. in' combination, a hollow pedestal, a springpressed shaft projecting therefrom and adapted yieldably to support articles, members movable on a pin and coperating to be brought into and out of tight frictional engagement with the shaft to control the yielding movement thereof, and a movable bar having a head engaging between said movable members for controlling the operation thereof.

2. 1n combination, a hollow pedestal, a springpressed shaft projecting therefrom and adapted yieldably to support articles, coperating members pivotally supported upon the pedestal and adapted to be brought into and out of frictional engagement with the shaft to control the yielding movement thereof, a movable bar having a head engaging between said coperating members t0 effect the frictional engagement thereof with the shaft, a pressure bar fulcrumed to said movable bar by which at will to vary the force of frictional engagement, and independent means for actuating said movable bar.
